I was hoping for some clarification on this particular code. I've always been under the impression that we could only bill this code once per palm, but I've recently received some pushback with providers stating they should be able to bill per digit treated. Optum's encoder does not allow for the use of the "F" modifiers, and it has a max unit of 2. Does anyone have any official guidance on this? Any help would be greatly appreciated. Thank you!
